[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0024] The following gives specific embodiments.

[0025] As Figures 1 to 5As shown in the embodiment of this utility model, a hole sealing structure includes a support frame 1; a fixed column 11 is fixedly connected to the support frame 1; a limiting ring 12 is fixedly connected to the fixed column 11; a telescopic rod 13 is fixedly connected to the fixed column 11; the telescopic rod 13 is located inside the limiting ring 12; a buffer block 14 is fixedly connected to the end of the telescopic rod 13; multiple fixing strips 15 are hinged to the buffer block 14; a stone slab 16 is provided on the support frame 1; multiple fixing holes 17 are opened on the stone slab 16; the fixing holes 17 and the support frame 1 are correspondingly arranged. The support frame 1 is placed on the structural wall at the hole, and then the support frame 1 and the structural wall at the hole are fixed with bolts. After the fixing is completed, the stone slab 16 is placed on the support frame 1. At this time, the fixing holes 17 opened on the stone slab 16 correspond to the fixing column 11. When the fixing column 11 enters the fixing hole 17, the telescopic rod... The buffer block 14 fixed to the upper part of the 13 contacts the inner wall of the fixing hole 17. At this time, the buffer block 14 is pressed down towards the fixing column 11. When the buffer block 14 is pressed down, the telescopic rod 13 is compressed. When the telescopic rod 13 is compressed, it drives the fixing strip 15 to move downward. When the fixing strip 15 moves downward, the fixing strip 15 contacts the edge of the limiting ring 12 fixed to the fixing column 11. At this time, the limiting ring 12 expands the multiple fixing strips 15 to all sides. When the fixing strip 15 is expanded, the end of the fixing strip 15 contacts the inner wall of the fixing hole 17. When the fixing strip 15 contacts the inner wall of the fixing hole 17, the stone slab 16 is fixed. By hinged to the buffer block 14, when the fixing strip 15 is expanded to all sides, the fixing strip 15 contacts the inner wall of the fixing hole 17, thereby fixing the fixing hole 17, reducing the situation where the stone slab 16 is placed directly on the support frame 1 during use, causing the stone slab 16 to shake.

[0026] like Figure 2 As shown, multiple brackets 2 are fixedly connected to the limiting ring 12; rollers 21 are rotatably connected to the brackets 2. When the telescopic rod 13 is pressed down, it drives the fixing strip 15 to move downward. When the fixing strip 15 moves to the designated position, the fixing strip 15 contacts the rollers 21 rotatably connected to the brackets 2. At this time, the rollers 21 support the fixing strip 15 and the fixing strip 15 rolls on the rollers 21. By fixing multiple brackets 2 to the limiting ring 12 and rotatably connecting rollers 21 to the brackets 2, the fixing strip 15 rolls on the surface of the rollers 21 when it contacts the rollers 21. This can reduce the situation where the fixing strip 15 directly contacts the edge of the limiting ring 12 and causes wear on the fixing strip 15. At the same time, it can make the fixing strip 15 more smoothly spread outward to complete the support and fixation work of the inner wall of the fixing hole 17.

[0027] like Figure 3As shown, a plurality of ball bearings 3 are rotatably connected to the fixing strip 15. The ball bearings 3 are located between the fixing strip 15 and the fixing hole 17. When the fixing strip 15 enters the fixing hole 17, the fixing strip 15 is spread outwards. At this time, the plurality of ball bearings 3 rotatably connected to the fixing strip 15 contact the inner wall of the fixing hole 17. When the ball bearings 3 roll on the inner wall of the fixing hole 17, the fixing strip 15 enters the fixing hole 17 more smoothly to complete the fixing work of the fixing hole 17. By rotatably connecting a plurality of ball bearings 3 to the fixing strip 15, when the ball bearings 3 contact the inner wall of the fixing hole 17, the ball bearings 3 roll on the inner wall of the fixing hole 17, which makes the fixing strip 15 enter the fixing hole 17 more smoothly to complete the fixing of the stone slab 16, and reduces the situation where the fixing strip 15 gets stuck when entering the fixing hole 17.

[0028] like Figure 4 As shown, a rubber block 4 is fixedly attached to the fixing strip 15; the rubber block 4 is located between the fixing strip 15 and the fixing hole 17. When the fixing strip 15 enters the fixing hole 17 to fix the stone slab 16, the rubber block 4 contacts the inner wall of the fixing hole 17. At this time, the friction between the fixing strip 15 and the fixing hole 17 increases. By fixing the rubber block 4 to the fixing strip 15, the friction increases when the rubber block 4 contacts the fixing hole 17, which allows the fixing strip 15 to contact the inner wall of the fixing hole 17 better, reducing the shaking of the stone slab 16 during use.

[0029] like Figure 5 As shown, an elastic rope 5 is fixedly connected to the fixing strip 15; the other end of the elastic rope 5 is fixedly connected to the limiting ring 12. When the fixing strip 15 is spread outwards to fix the inner wall of the fixing hole 17, the elastic rope 5 is stretched. When it is not necessary to fix the inner wall of the fixing hole 17, the elastic rope 5 pulls the fixing strip 15 back to its original position under its own elastic force. By fixing the fixing strip 15 with an elastic rope 5, when the fixing strip 15 is not used, the elastic rope 5 pulls the fixing strip 15 back to its original position, which makes the subsequent use of the fixing strip 15 more convenient.

[0030] like Figure 5 As shown, an elastic cloth 6 is fixedly connected to the limiting ring 12; the other end of the elastic cloth 6 is fixedly connected to the buffer block 14; the telescopic rod 13 is located inside the elastic cloth 6. When the telescopic rod 13 is compressed, it drives the elastic cloth 6 to be compressed at the same time. When the compression of the telescopic rod 13 is released, the telescopic rod 13 moves upward. When the telescopic rod 13 moves upward, it drives the elastic cloth 6 to move accordingly. At this time, the elastic cloth 6 is stretched. When the elastic cloth 6 is stretched, it covers the telescopic rod 13. By fixing the elastic cloth 6 to the limiting ring 12, and covering the telescopic rod 13 when the elastic cloth 6 is stretched, the amount of dust and impurities falling into the limiting ring 12 during use is reduced, which may cause the telescopic rod 13 to move and get stuck during use.

[0031] Working principle: the stone plate 16 is placed on the support frame 1, at this time the fixed hole 17 opened on the stone plate 16 corresponds to the fixed column 11, when the fixed column 11 enters the inside of the fixed hole 17, the buffer block 14 fixed on the telescopic rod 13 contacts the inner side wall of the fixed hole 17, at this time the buffer block 14 is pressed downward to the fixed column 11, when the buffer block 14 is pressed downward, the telescopic rod 13 is compressed, when the telescopic rod 13 is compressed, the fixed strip 15 is driven to move downward, when the fixed strip 15 moves downward, the fixed strip 15 and the limiting ring 12 fixed on the fixed column 11 edge contact, at this time the limiting ring 12 supports the multiple fixed strips 15 to the four directions, when the fixed strip 15 is supported, the fixed strip 15 end and the inner side wall of the fixed hole 17 contact, when the fixed strip 15 and the inner side wall of the fixed hole 17 contact, the stone plate 16 is fixed, when the telescopic rod 13 is pressed downward, the fixed strip 15 is driven to move downward, when the fixed strip 15 moves to the specified position, the fixed strip 15 and the roller 21 rotatably connected on the support 2 contact, at this time the roller 21 supports the fixed strip 15 and the fixed strip 15 rolls on the roller 21, when the fixed strip 15 enters the inside of the fixed hole 17, the fixed strip 15 is supported to the four directions, at this time the multiple rolling balls 3 rotatably connected on the fixed strip 15 and the inner side wall of the fixed hole 17 contact, when the rolling ball 3 rolls on the inner side wall of the fixed hole 17, the fixed strip 15 more smoothly enters the inside of the fixed hole 17 and completes the fixed work of the fixed hole 17, when the fixed strip 15 enters the inside of the fixed hole 17 and fixes the stone plate 16, the rubber block 4 and the inner side wall of the fixed hole 17 contact, at this time the friction between the fixed strip 15 and the fixed hole 17 becomes larger, when the fixed strip 15 is supported to the four directions and fixes the inner side wall of the fixed hole 17, the elastic rope 5 is stretched, when the inner side wall of the fixed hole 17 is not needed to be fixed, the elastic rope 5 stretches the fixed strip 15 back to the original position under the action of the elastic force, when the telescopic rod 13 is compressed, the elastic cloth 6 is compressed at the same time, when the compression of the telescopic rod 13 is released, the telescopic rod 13 moves upward, when the telescopic rod 13 moves upward, the elastic cloth 6 moves with it, at this time the elastic cloth 6 is stretched, when the elastic cloth 6 is stretched, the telescopic rod 13 is covered.
